Dental Sealants are a highly effective, non-invasive preventive treatment designed to protect the chewing surfaces of the back teeth (molars and premolars) from decay. These back teeth have deep grooves and pits where food particles and bacteria often get trapped, even with careful brushing. At Prime Smile Dental, we apply a thin, durable, plastic coating to these vulnerable areas, effectively sealing them off and dramatically lowering the risk of cavities.
A dental sealant is a thin, liquid plastic material that is painted onto the biting surfaces of the back teeth. The liquid flows into the deep grooves and fissures, and then quickly hardens, creating a smooth, protective barrier.
Key facts about sealants:
Sealants are a cornerstone of modern preventive dentistry and an excellent investment in your child’s (and sometimes adult’s) long-term oral health.

Studies show that sealants can reduce the risk of decay in the sealed area by nearly 80% for several years after application.

The application is simple, requires no anesthesia, and takes only a few minutes per tooth, making it ideal for children and anxious patients.

By preventing decay, sealants ensure that the natural tooth enamel remains intact, avoiding the need for future fillings.

The cost of a sealant is significantly less than the cost of filling a decayed tooth, making it a smart financial choice.
The sealant procedure is efficient, comfortable, and typically performed by the dental hygienist:
Step 1Cleaning and Preparation
The tooth surface is thoroughly cleaned to remove all plaque and debris. The tooth is then etched with a mild acid solution for a few seconds to microscopically prepare the enamel surface for optimal bonding.
Step 2Rinsing and Drying
The etching solution is rinsed off, and the tooth is completely dried. Keeping the tooth isolated and dry is critical for the sealant to bond effectively.
Step 3Sealant Application
The liquid sealant material is carefully painted directly into the pits and fissures of the chewing surface.
Step 4Curing
A special curing light is used for a few seconds to harden the liquid sealant, creating a durable, plastic shield. The process is then checked for a comfortable bite.
Sealants are primarily recommended for specific patients and teeth:
Sealants should be applied to the permanent first and second molars immediately after they fully erupt (around ages 6 and 12, respectively).
Individuals with teeth that have deep grooves and fissures but no existing decay.
Those who struggle with plaque control or have medical conditions that compromise saliva flow, increasing decay risk.
Sealants are only effective on teeth that have not yet had any decay or fillings on the chewing surface.
The cost of dental sealants in Aurora can vary based on how many teeth are being treated and whether sealants are placed on one or both arches. Sealants are most commonly applied to the back teeth (molars and premolars), where deep grooves can trap food and bacteria. Pricing may also depend on whether sealants are done during a routine checkup and cleaning or as a separate visit.
At Prime Smile Dental in Aurora, Ontario, we’ll assess the teeth first to confirm if sealants are appropriate and which teeth would benefit most. Our team can also review your insurance or CDCP details and help you understand expected costs before treatment whenever possible.
Dental sealants at Prime Smile Dental are provided under the guidance of Dr. Shideh Khalilakbar, our lead dentist. Dr. Khalilakbar focuses on preventive care and helps patients understand simple steps that can reduce the risk of cavities—especially for children and teens as permanent molars come in.

Sealants are highly effective, but they only protect the chewing surfaces where they are applied. You still need to brush and floss to protect the smooth sides of the teeth and the areas between them.
Absolutely not. The procedure is entirely non-invasive, painless, and involves only cleaning and painting the surface of the tooth. No anesthesia is needed.
Yes. While the primary benefit is for children’s new molars, adults who have deep grooves and no existing decay on their molars can also benefit from sealants, especially if they are prone to cavities.
